TQ `@ZZ whom it may Concern.: A p y Be it I:known thatwe, .GEORGEF..A DALE and Miene-nad. MEARA, citirlens of tiheUi'iited States, residing, respectively, yin,Trenton, New Jersey, and Philadelphia, Fennsyl; vania, have invented certainA Improvements in Hollow-Tile AFlooil Construction, of which the followingiis a -s'peciii'cation Y Our invention relatesto certain improvements in what i'sknown yas .a two-wayroor construction, in which tiles are set in con! crete, whiclris reiniorcedby transverse and longitudinal bars. y i

The ob'e'ctV ofour invention-is to maire atileso thaty ktwo tile "sections, similarv in construction, .can be assembled-t0 form a tile uni-t closed attop and bottom and on all four sides. lVhen severaloi these units are located ingaV floor .and surrounded on theysides with concrete, y. the; top and Vbottom of said' tile units vactas compression niem-` In the accompanying.drawings: n

Fig. 1()` is a View illustrating another form of tile.

Referring to the drawings, 1 is the floor. 2 are posts spaced a given distance apart. 3 and 4 are concrete beams which extend from one post to the other. In the space between these beams is a series of tile units 5 spaced apart, as shown in Figs. 1, 2 and. In the spaces between the tile units are longitudinal bars 6 and transverse bars 7. The

Spa/ce vbetween the tile units is filled with concrete. l This construction 'forms what is known as a two-way {ioor construction? Each tile unit consists oi' two tile sections I 8 and' 9. These tile sectionsa-re made,` in the presentl instance, ironia tile .block 1C), as illustrated inlFig'.l 5. This tile blocli has a continuous top member lland a continu- .is cut, asfsliown in'Fig.` 6, into 1 ousvbottom zmember r12*- connected by" sides fdivision is in amplane, or planes, parallelp,v

to the generalplane o'flthe. floor.'

InFig; 8, a modification of the invention' is illustratethin which theftwo tile sections 8'il andQfare'identical inform, each' having a sectionwliieh extends over the tu'llvwidtli of the t'1le`,za's infFig. 9, and having" vertical websv 1,6', iwhicl'rcro'ssreach other, as shown'.

Projections "1"?" on one section are adapted'to recesses 18 in the other section so that when the two tile sections are assembled, as in Fig. 9, the upper surface of one section and the lower surface of the other section form continuous members, and the parting is on 1 planes parallel to the plane of the floor.V

modified form of a tile section having a flat unbroken surface 1la connected b webs 19 with an inner web 20 and having ollow flanges 13a. This particular construction forms the subject of a separate application for patent. y

In assembling the tile units in a vfloor, they are spaced apart, as shown in Figs. 1, 2 and 3. The metallic rods areplaced in position, after which the concrete is poured in the spaces: between the tile units to the Same depth as the tile units, as shown in Fig. 2, so that the lower portion oi each lower tile can act as a lower compression member, as the concrete is in direct Contact with the tile. The upper portion of the upper tile can act as an upper compression member, as the concrete is in direct contact therewith.

Vhile the term hollow tile units is used in the claims, it will be understood that the units may be made of baked clay, concrete, with or without reinforcements, or any other material that will sustain a load under compression.

`We claim:

l. A hollow tile unit formed of two similar tile sections, each of said sections having end flanges adapted to cooperate with and overlap the sides of the opposing section to form a tile unit closed on all four sides, the end edges of said flanges forming oppositely presented external shoulders, and means for maintaining the said end-edges of the flanges between the top and bottom planes of the assembled unit.

2. A hollow tile unit formed of two similar tile sections, each having parallel end flanges and parallel webs intermediate, and of less length than, the end flanges, the tile sections in the unit having their flanges at right angles, with the end flanges of each section closing the sides of the other section and offset outwardly beyond said sides to form external shoulders, and the intermediate webs engaging one another and serving to hold the ends of the said shoulderforming flanges between the top and bottom surfaces of the unit.

8. A hollow tile unit comprising two similar tile sections each having a top member and two oppositely arranged end fianges, the distance between the inner surfaces of said end flanges beingV equal tothe width of the top members so that when one section is inverted, turned at right angles and assembled within the other, the two sections form a tile unit closed on allfour sides and having oppositely presented external shoulders, and means for maintaining the shoulderforming end edges of the said end flanges between the top and bottom planes of the assembled unit.

4l. A hollow tile unit comprising two similar tile sections, each having a top member and two oppositely arranged end flanges, the distance between the inner surfaces of said end flanges being equal to the width of the top members so that when one section is inverted, turned at right angles and assembled within the other, the two sections form a tile unit closed on all four sides and having oppositely presented external shoulders, and webs carried by each top member between said flanges adapted to support the sections to maintain the upper and lower edges of the said end flanges between the top and bottom planes of the assembled unit.

5. A hollow tile unit comprising two similar tile sections, 'each having a top member and two oppositely arranged end flanges, the distance between the inner surfaces of said end flanges being equal to the width of the top members so that when one section is inverted, turned at right angles and assembled within the other, the two sections form a tile unit closed on all four sides and having oppositely presented external shoulders, and a series of inwardly projecting' webs carried by each top member between said flanges, said webs being less in height than the end flanges and when engaged, supporting the sections to maintain the upper and lower edges of the said end flanges between the top and bottom planes of the assembled unit.
